The Jesus Itinerary

[John V]

Wrong. I'm not adding to the text.

Yes, you are. Watch:

"These people came to that house to visit so and so" suggests, unless otherwise noted in the story, that the house belongs to "so and so". I think it's fair to say everyone would read it that way but for your need to square it with Luke, whereupon you write a "good explanation" for it.

In sum, my explanation for the mysterious house is:
"That's his house"

There it is - you added to the text.

Your explanation for the mysterious house is roughly,
"Joseph arrived for the census, went back to Nazareth, then returned to Bethlehem because he got a great job offer and then had to flee to Egypt."

Occam's Razor.

No, my explanation is - it's a house. I don't know whose. Anything more is an explanation to your addition to the text, not the text itself.

It's a house. We don't know whose. Simplest interpretation. Occam's Razor.
